Java vulnerability analysis and mitigation

CVE-2022-34790 is a stored cross-site scripting (XSS) vulnerability affecting the Jenkins eXtreme Feedback Panel Plugin versions 2.0.1 and earlier. The vulnerability was disclosed on June 30, 2022, and affects the plugin's handling of job names in tooltips (Jenkins Advisory).

The vulnerability exists because the eXtreme Feedback Panel Plugin fails to properly escape job names when displaying them in tooltips. This results in a stored cross-site scripting vulnerability that can be exploited by attackers who have Item/Configure permission in Jenkins. The severity of this vulnerability is rated as High according to the CVSS scoring system (Jenkins Advisory).

The vulnerability allows attackers with Item/Configure permission to inject and execute malicious JavaScript code in the context of other users' browsers who view the affected tooltips. This could potentially lead to session hijacking, credential theft, or other malicious actions performed in the context of the victim's browser session (Jenkins Advisory).

As of the advisory's publication date, there is no fix available for this vulnerability in the eXtreme Feedback Panel Plugin. Users should consider restricting Item/Configure permissions to trusted users only and potentially disabling the plugin if the security risk is deemed too high (Jenkins Advisory).
